Does any program that Iran has at the end of this--at the end of any agreement, does it allow it as a practical matter to break out to get enough material for a nuclear weapon?

There is no right to enrich. We have been very clear about that.

There are different groups. There are different camps. There are lots of people who do not want an agreement under any terms.

First, in terms of what we are concerned about, we are most concerned about what our partners think, not what Iran thinks.

We have worked with Congress in these sanctions to ensure that as the sanctions are enacted and as they are applied, we do it in a way to hold together the international coalition.

If Congress had been asked to vote on the interim agreement... many Members... might have voted it down.

Congress has played a critical and indeed lead role getting us to where we are.

we are not chasing any deals. In fact, if we had been chasing a deal, we could have taken a deal months ago.

I think that what I heard Senator Menendez say and then Senator Schumer say--not having seen the letter, I would not want to comment on it in detail.

the President has been clear that the United States will do what it must to prevent Iran from acquiring a nuclear weapon.

Ultimately, even if they agree to a short suspension, that is their goal in the long term.

Our best judgment right now is this, and I think, Senator, you pointed to something very important.
